HEAD-MOUNT DISPLAY - A system and method is provided for varying the apparent distance of a virtual image projected by a head-mounted display. The distance between the user and an object being viewed by the user is determined. Then, the focal distance of an eyepiece optical system in the head-mounted display is adjusted to provide a virtual image at an apparent distance that corresponds to the determined distance. The user thereby experiences an approximately seamless overlay in sharp focus of the virtual image from the display and the three-dimensional binocular image being viewed. For example, when viewing a movie screen, or other object at infinity, the focal length is adjusted to provide a virtual image at or near optical infinity. Likewise, when reading a book, or inspecting another object in close proximity, the focal length is adjusted to provide the virtual image at a nearby apparent distance.

Executable Component Injection Utilizing Hotpatch Mechanisms - Techniques for causing a component loader associated with a hotpatch mechanism to execute a user-mode component which, when executed, creates a user-mode process, thread, or held reference are described herein. The component may further indicate to the component loader that it lacks hotpatch data, causing the component loader to unload the component. In some implementations, a kernel-mode module may initially provide the component to the hotpatch mechanism with an entrypoint of the component set to zero and with hotpatch data for the component loader. The hotpatch mechanism may apply the hotpatch data, modifying the component loader such that the component loader requests execute rights for a section object for the component. The kernel-mode module may then set the entrypoint such that the component becomes executable, and provides the section object and component to the hotpatch mechanism to cause the component loader to execute the component.
